Attostreaking with metallic nano-objects

Full field imaging of isolated metallic nano objects

Acousto-plasmonic hot spots in metallic nano-objects.

We investigate the acousto-plasmonic dynamics of metallic nano-objects by means of resonant Raman scattering and time-resolved femtosecond transient absorption. We observe an unexpectedly strong acoustic vibration band in the Raman scattering of silver nanocolumns, usually not found in isolated nano-objects. The frequency and the polarization of this unexpected Raman band allow us to assign it ...

Forging of metallic nano-objects for the fabrication of submicron-size components

In recent years, nanoscale fabrication has developed considerably, but the fabrication of free-standing nanosize components is still a great challenge. The fabrication of metallic nanocomponents utilizing three basic steps is demonstrated here. First, metallic alloys are used as factories to produce a metallic raw stock of nano-objects/nanoparticles in large numbers. These objects are then isol...

Molecular nano-junctions formed with different metallic electrodes

Issue no Total pages First page Last page File name Date req Artnum Cover date Abstract Conductance of nanoscale junctions consisting of a molecular monolayer in contact with different metal electrodes is studied. The characteristic energy scales of conductance are determined from the temperature dependence and from the non-linear current–voltage characteristics. Conductance measured at small b...

Metallic nano-particles for trapping light

We study metallic nano-particles for light trapping by investigating the optical absorption efficiency of the hydrogenated amorphous silicon thin film with and without metallic nano-particles on its top. The size and shape of these nano-particles are investigated as to their roles of light trapping: scattering light to the absorption medium and converting light to surface plasmons. The optical ...
